Abstract
A multi-chamber injection device includes multiple syringes. The multiple syringes may be arrayed in a circular, linear, or other format. In some implementations, a needle, port, or similar may be shared by all the syringes in configuration that allows only one syringe to deliver contents at a time while blocking the other syringes from delivering their respective contents. In some implementations, the syringes may be all stored in the same container. One or more of the chambers of a multi-chamber injection device may be preloaded with medication. Different medications may be loaded into different chambers. The medications may be selected to treat the same medical condition.

31. A multi-chamber syringe comprising:
-
three or more chambers arranged perpendicular to each other and perpendicular to a central axis; plungers associated with each of the chambers; and an outlet body rotatably connected to the chamber such that at least a portion of the outlet body rotates around the central axis positioning an outlet in fluid communication with one of the chambers while blocking release of fluid from the other chambers; wherein two or more of the chambers contain different drugs both usable to treat a same medical condition. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A device comprising:
-
a plurality of syringes each having a hollow needle, a chamber, a plunger associated with the chamber, and a rotatable valve connecting the needle to the chamber; wherein the rotatable valve rotates along an axis of rotation perpendicular to a long dimension of the chamber; wherein the valve is open allowing fluid to pass between the chamber to the needle when the needle is rotated parallel to the long dimension of the chamber with a tip of the needle pointing away from the plunger; and wherein the valve is closed preventing fluid communication between the chamber and the needle when the needle is rotated parallel to the long dimension of the chamber with the tip of the needle pointing toward the plunger. - View Dependent Claims (45, 46, 47, 48, 49, 50)
